Japan NGK SPARK PLUG CO., LTD.
At the Marathon EXPO held at the Nagoya Women's Marathon 2021 and the Nagoya City Marathon 2021, we offered earth-friendly aroma stones to 500 people who visited our booth and posted it on SNS with hashtags.
This aroma stone, a recyclable and sustainable material made of 100% natural material, is made by ceramics that harden with CO2. One stone absorbs CO2 equivalent to about 3.8 500ml bottles. By absorbing and immobilizing CO2, its emissions are reduced by 70% compared to the conventional manufacturing method.
